Fair to Good Cut

Simulant (Likely Cubic Zirconia or Glass) - Round Brilliant

Carat

Estimated reaching 0.50 - 0.75 carats based on diameter relative to fingertips

Color

Colorless (Equivalent to D-E-F range)

Clarity

Eye Clean (Equivalent to VVS/VS visually from distance)

Shape

Round Brilliant

Overall Assessment

Based on the high dispersion (fire) and the specific nature of the light reflection, this specimen appears to be a diamond simulant rather than a natural or lab-grown carbon diamond. It serves well for aesthetic purposes but lacks the intrinsic value of a gemstone.

Cut Quality

Fair to Good

Brilliance

Moderate; shows some white light return but lacks the depth of a natural diamond

Fire

High; the dispersion of light into spectral colors is more pronounced than a natural diamond of this size

Scintillation

Moderate; the sparkle pattern is somewhat flat

Proportions

Standard commercial proportions with a high crown and potentially shallow pavilion contributing to the 'windowing' effect

Symmetry

Fair; misalignment of facets visible under magnification

Polish

High gloss, typical of synthetic simulants

Fluorescence

Not detectable via standard photograph

Inclusions

None visible to the naked eye; lacks the typical carbon characteristics of a natural diamond

Blemishes

Minor surface abrasions consistent with wear on a softer material than diamond

Origin

Factory produced (Synthetic)

Treatment Detection

Material is homogenous; no treatments detected as the base material is lab-made

Estimated Value

$5 - $20 USD (replacement cost for a simulant)

Certification Estimate

Unlikely to be graded by GIA or AGS; would likely be identified as a simulant by IGI

Investment Potential

Negligible; simulants do not retain resale value

Similar Diamonds

Swarovski Zirconia or high-quality glass crystals

Setting Suggestions

Ideal for costume jewelry, silver earrings, or low-cost fashion rings

Care & Maintenance

Clean with warm soapy water and a soft cloth; avoid harsh chemicals which may cloud the surface

Interesting Facts

Cubic Zirconia is heavier than diamond but much softer, making it prone to scratches over time
